Sometimes cameras need to be placed in areas where wiring would obviously give away the fact that the camera is hidden. When this is the case a 2.4 Ghz wireless hidden camera is the perfect solution for the job.
Unless a camera has its own “on-board” Digital Video Recorder or DVR, it will need a video transmission cable, commonly RG59. However a 2.4 Ghz wireless hidden camera can eliminate the need for cables by sending the video transmission signal via radio waves.
It sends the radio waves using an on-board transmitter and antenna that use the 2.4 Ghz technology. This is the same technology that is often used by many land-line based wireless telephones.

There are times when it is necessary to use a covert security hidden camera. Security Camera King offers a full range of hidden or disguised cameras, camera units that contain their own Digital Video Recorder or DVR, and high-quality low visibility powered microphones.
What exactly is a covert security hidden camera? It’s actually nothing more than a camera that captures digital video and audio (depending on the model) without the knowledge of the subject being recorded. The camera can be a standard sized digital video camera or it can be a very small disguised camera like our Phillips screw-head camera.

If you need security and surveillance coverage in poorly lit or no light areas, you should try using an infrared camera system. In the following article we’ll talk about how these cameras work and what to look (out) for when purchasing a system.
Under normal daylight conditions a digital video security camera utilizes the light waves that are reflected from the objects in its field of vision. It does this by using a lens to focus the entire image onto a sensor chip that is usually 1/4 or 1/3 of an inch square. The sensor chips work by converting the light energy into a small electrical impulse which can be measured and therefore ultimately used to create a digital video image.

Video security systems are fast becoming the “wave” of the future. Not only can they document events as they occur, but with Internet technology and other electronic technology advancements, they can even act as burglar alarms and alert you when possible illegal events occur.
A basic digital video security system is a component system that consists of three major components:
1) One to many cameras;
2) A DVR or Digital Video Recorder; and,
3) A monitor or monitors

It’s been said that someday almost every electronic appliance will be tied to the Internet; so enters the IP camera and DVR. Don’t take this the wrong way, this is definitely a good thing for the digital video security and surveillance system industry. Providing digital video systems with a mechanism to connect to the Internet places the power of versatility and omnipresence in the user’s hand. But what exactly does IP mean and how do these devices work? We’ll try to answer these questions in the following article.
